The Lilac club explains the Cambridge Blue through a cross involving blue Beverens and Havanas, describing the result as dilute chocolate. Modern rabbit research on MLPH supplies a molecular context for dilution, but is not a census of Lilac genomes. These two evidence types complement rather than replace one another: the club account concerns breeding history, while the research examines how pigment distribution can change. A breeder's color term should not be presented as if every animal carrying it has undergone laboratory confirmation. In particular, one color cannot tell us the breed's complete genetic diversity.
